Floribunda rose plant named ‘POULcs009’

ABSTRACT

A new garden rose plant of the floribunda class which has abundant, pink flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrid.

Variety denomination: ‘POULcs009’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between the female parent ‘POULdrik’ described and illustrated in U.S. Plant Pat. No. 12,557 issued on Apr. 23, 2002, and the male parent an unnamed seedling. The two parents were crossed during the summer of 1994 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULcs009’.

The new variety may be distinguished from its female seed parent, ‘POULdrik’ by the following combination of characteristics:

-   -   1. While the seed parent ‘POULdrik’ has a flower color of Red         Group 52C the same of ‘POULcs009’ is Red-Purple Group 65D with         intonations of Red-Purple Group 64D.     -   2. While the seed parent ‘POULdrik’ has 14 to 18 petals,         ‘POULcs009’ has 50.     -   3. While the seed parent ‘POULdrik’ has a flower diameter of 60         mm, the same of ‘POULcs009’ is 50 mm.

The new variety may be distinguished from its unnamed male pollen parent by the following combination of characteristics:

-   -   1. The pollen parent has very pale pink flowers, while         ‘POULcs009’ has medium pink flowers.     -   2. The pollen parent a low growth habit, ranging from 40 to 60         cm, while ‘POULcs009’ has an average height of 76 cm.     -   3. Flowers of ‘POULcs009’ have a longer lasting quality on the         plant than those of the pollen parent.

The objective of the hybridization of this rose variety was to create a new and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant pink flowers;     -   2. Vigorous, but compact and even growth when propagated both as         a budded rose and on its own roots;     -   3. Disease resistance;     -   4. Flower color which does not fade;     -   5. Well suited to normal cultural practices in the garden and in         containers.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘POULcs009’ from all other varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 1994 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULcs009’ was selected in the spring 1995 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULcs009’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July, 1995. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULcs009’ are true to type and are transmitted from one generation to the next.
